You may return all set aside cards to your discard pile. If you do, +$1 for each card returned.
----
When you gain a Curse, Ruins, or Victory card, you may reveal this from your hand. If you do, set aside the gained card.
The idea is that you still gain the "bad" cards, but don't have to have them in your deck (they will be added at the end of the game).
If you want to have a big turn, you can return them to your deck and they'll get shuffled in eventually.
I don't know whether adding them to the discard is fine, or it should be deck or hand, but it's just the instant-Island effect which I think is pretty cute.
